OG13 SC Q#77

[AnooshehK513]

Dear MGMAT,

I am already enrolled in your online interact class and I must say that I love it. So First, Thank you.
Now I have two questions regarding the following question from OG 13 SC #77 which after watching the video on navigator and reading the solution still remains puzzling for me. Could you kindly help me with the following:

1. Was it correct if instead of "had been allowed to dump" it was written "were allowed to dump"? or is it the case that only "are allowed to dump" works?

2. I have noticed that in some answers we have "Amount of phosphates" and in other ones we have phosphate amount. Isn't phosphates plural and hence using "amount" wrong with it? Should it not be "Amount of Phosphate"? or "Phosphate Amount"?

Hello! I'm so glad that you're enjoying the Interact program. I'm sorry, but I had to remove your question—please make sure to look through the forum guidelines before posting. GMAC, the makers of the GMAT, do not permit their Official Guide questions to be posted online. (I know that other forums still do so...but we follow the rules. )

Since you are an Interact student, you can send an email to gmat@manhattanprep.com to ask your question. (Course students can ask their instructors.)

For future: you can post any MPrep questions on the forums (just make sure to post in the correct folder). You can also post any free-source official questions (such as from the free materials in GMATPrep)—but for OG questions, send an email to the address above.
